I get what you mean when you say that the designer can’t edit it anymore. That’s okay. I’ll talk about ways things that you can focus on for future covers then.
So when I look at your cover, the first thing I see is the moon. That’s pretty natural, as your eyes tend to be drawn towards the brightest and darkest colors in the composition. Now, when I look at the moon, I notice two things. The first, is that the moon is squished. It’s not really a big thing, and most people who are glancing at your cover won’t notice it, but it is kind of an odd shape if you stare at it. The second thing that I notice is the brightness and the contrast are a little off. What I mean when I say that is when you’re looking at the image, you want there to be a balance. So when you look at the moon, you want to see both the moon AND the wolf at first glance. But because of the overwhelming brightness and size of the moon, the moon kind of washes out the wolf and it takes you a moment to focus in on it to see it for what it really is.
The answer to this is pretty simple: you can ask the designer to lower the brightness of the moon or just make the wolf larger than before.
The next thing I notice is the amount of detail. I know this is pretty standard since fantasy covers tend to include lots of detail to help set up the world, but in some places it was a bit much. For sample, take a look at the sky. If the moon was really that bright, you probably wouldn’t see all the stars that exist. This also affects the balance of your cover as your cover is really top-heavy and it’s relying solely on the text at the bottom to fill up the rest of the image. Unfortunately, it doesn’t quite fill it all the way, meaning that your eyes will naturally drift more towards the top than towards the bottom.
Answer: Remove some of the stars, or leave the sky darkened and put in more texture around the bottom. Not something obvious and that contains a lot of white, like stars. But something subtle. These can be trees, rocks, mountains, etc. Just a couple different shapes that are a little bit lighter than the background that helps balance the image a little bit better.
After that, I notice the title. The text is really quite beautiful, but if it’s the third thing I’m noticing, something’s wrong. The title of your story should really be the first or second thing someone notices when looking at your book. You want it to be this way because then it will stand out more. People’s memories for cover designs tend to get blurred together, especially when there’s a lot of covers right next to each other and many of them look very alike, like what we see here on Wattpad. This means that your title needs to be one of the first things they see so that they know your story, even if they decide not to click on it. (Also, since your image is top-heavy, the actual text I see first is the Legend Series: 1. but I already explained how you can fix that so it’s not the first bit of text your eyes focus on which is: decluttering everything else.)
Answer: Raise the brightness in the title. If you turn the title white, you can still achieve that purple, glow-y feel that you’ve got going but through filters like “outward glow”, “inward glow”, etc. (I’d go more into detail about the specifics but since you told me that you had someone design the covers for you, that wouldn’t really help you that much…)
The second to last thing that I see, is the text at the bottom. One thing that really confused me was why your name and your tag line (a tag line is the part that says, “like fire and ice”) were the same size. Usually, to help keep your name more of the focus, like the title, you make it larger. The second thing that confused me was why the tag line was brighter than your name. Point is: name needs to be larger and brighter, not outshining the title or the top text in anyway, but certainly not the same size as the tag line or darker.
And finally, the last thing I noticed, is the corners. At the bottom they look fantastic because they’re very clean cut and you can tell what they are. At the top they’re different colors and the right corner literally blends into the image. I didn’t see it at first until I noticed the other three corners. However, while the corners are pretty, I don’t think your cover actually needs them. I think it’s another detail that only clutters up the image and gives the appearance of too much going on in such a short time.
Maybe ask your designer to give you two copies next time, one with the corners and one without. If you really love them, keep them. But if you think it looks better without, then by all means.
Overall, your cover is actually pretty decent. I know that I made a lot of points but that’s mostly because I wanted to be thorough. If there are two things that I have to suggest you really, really focus on, it’s the balance of the image and making sure that your text is more of a focus. Those are the two most important things that can really help your cover in this situation. And also, tell your cover designer that the font they used is beautiful. If you’re going for magical, it really does have that magical vibe to it that makes it interesting to look at.
